A gadget which makes water out of air could become the greatest household invention since the microwave.http://www.ks5u.com/gaokao/beijing/ Using the same technology as a dehumidifier ,the Water Mill is able to create a ready supply of drinking water because it can always get from an unlimited source--the air.http://www.ks5u.com/gaokao/beijing/ The company behind the machine says not only does it offer an alternative to bottled water inhttp://www.ks5u.com/gaokao/beijing/ developed countries, but it is a solution for the millions who face a daily water shortage.http://www.ks5u.com/gaokao/beijing/ The machine works by drawing in wet air through a filter and over a cooling instrument which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases. In keeping with its eco-development, the machine uses the same amount of electricity as three lights.    Inventor Jonathan Ritchey said, "The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable." The machine, which is about 3 feet wide, is likely to cost PS800 when it goes on sale here in the spring. Its maker, Canadian Firm Element Four, roughly calculates that a liter of water costs around 20 pence to produce. Environmentalists state that half the world's population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking. The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won't be much of a problem. What does the passage lead us to believe?http://www.ks5u.com/gaokao/beijing/ A) The cost of water will go up. B) Bottled water will disappear soon. C) The machine is energy saving. D) The machine will be popular worldwide.

Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly , for example by dipping it in water , it will be very hard but also very brittle ---that is , It will break easily. Metal that has been annealed is soft but does not break as easily . It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly , for a certain length of time. The longer the heated metal takes to cool slowly , the softer it becomes . Annealing can also be used on other materials, such as glass. Why do people put hot metal in water ?   _ A) To make it hard B) To make it soft C) To make it cool D) To make it brittle

New software is able to analyze exactly how many hairs there are in a patch of skin and could help in testing the effectiveness of baldness  treatments and depilatory  creams, say Australian researchers. Researchers from CSIRO Mathematical and Information Sciences in prefix = st1 /Sydneyreport their findings in the November issue of the journalSkin Research and Technology. The software, developed with a UKcompany, will make it easier for researchers developing hair removal creams to accurately assess how well they work, says Dr Pascal Vallotton. "Up to now they were counting the number of hairs that survived after treatment by hand. That's hard work and it's difficult because you may count a hair twice or you may miss it." he said. The software relies on images captured by a small flatbed scanner  pressed onto the skin. Using a mathematical algorithm , the software then identifies and traces each individual hair based on an understanding of a hair's unique features, such as its   straightness.  The software is able to distinguish between hairs and other features on the skin such as wounds or moles .  "Our skin irregularities  make it difficult to say this is a hair or this is a mole," Dr Vallotton said.  Comparison between earlier and later images can also determine if hair is growing quickly or slowly, he says. Unfortunately, to check the accuracy of the software, the researchers still had to adopt the old-fashioned method of counting hairs, helped by volunteers from neighboring labs who put their skins on the line for science. "We had 12 volunteers, mostly from neighboring labs, and we acquired images of hair before and after treatment," Dr Vallotton said. To ensure an accurate count, the individual hairs had to be marked off as they were counted, but after such a laborious process, the researchers were pleased to discover the software results were comparable to the manual  count. Dr Vallotton says the software could also be useful in testing the effectiveness of balding  treatments and counting or tracing... What do we know about the new software? A) It has replaced human labor completely. B) It is mainly used to detect hair problems. C) It can be used for develop new medicine. D) It can be used to test medical treatments.
